Self-bearing type multiplex mouse-bite-proof optical cable capable of being recognized at night

Abstract

The invention provides a self-bearing type multiplex mouse-bite-proof optical cable capable of being recognized at night. The self-bearing type multiplex mouse-bite-proof optical cable comprises an optical cable body, wherein the optical cable body sequentially comprises an outer sheath layer, a middle protection layer, a mouse-proof layer, an inner protection layer, a protection layer, a center reinforcing element and a plurality of cable cores from outside to inside; the center reinforcing element and the cable cores are respectively arranged in the protection layer; the cable cores surroundthe periphery of the center reinforcing element; at least one marking strip is arranged on the outer surface of the middle protection layer; the self-bearing type multiplex mouse-bite-proof optical cable also comprises a hanging wire and a connecting bar; the hanging wire comprises a hanging wire outer sheath layer and a hanging wire reinforcing bar; the upper and lower ends of the connecting barare respectively connected with the hanging wire outer sheath layer and the outer sheath layer and are integrally formed. The bite of mice and ants on the optical cable body and the marking strip canbe prevented; the occurrence of conditions of optical cable water leakage, fracture and unclear mark strips can be avoided; the position of each cable core can be conveniently recognized in dark environment; the service life is effectively prolonged; when the protection layers, the center reinforcing elements and the hanging wire reinforcing bars are respectively made of nonmetallic materials, the optical cable has the lightning protection effects.

Description

technical field [0001] The invention belongs to the technical field of self-supporting optical cables, in particular to a self-supporting multiple anti-rat-biting optical cables that can be identified at night. Background technique [0002] Self-supporting optical cable is a kind of optical cable whose self-strengthening components can bear its own weight and external load. It is generally used overhead on power poles and towers. Since the optical cable is erected at high altitude for a long time, and the self-weight should be reduced as much as possible to prevent the optical cable from sagging under the condition of sufficient mechanical strength, the self-supporting optical cable generally does not have multiple layers of protection, and some even do not have protection. However, in country alleys, due to the influence of geographical location and environment, self-supporting optical cables will inevitably be connected to electric poles near the ground or buried undergrou...

AI Technical Summary

Problems solved by technology

The disadvantage is that the luminous function of the marking strip is more likely to attract rats and ants, and the inner protective layer can only be used to prevent water leakage from intruding into the cable core due to the cracking of the outer sheath, so it cannot prevent further gnawing by rats and ants
